Definitions
- the present invention relates to rocker switch units particularly for small household and electronic appliances.
- the present invention has for its aim the presentation of a rocker switch unit which, by arrangement and combination of parts, proves more advantageous in terms of manufacture, assembly and costs and is suitable for applying to 19 x 13 mm and 27 x 12 mm boring templates.
- Another aim of the present invention is to provide a rocker switch unit featuring never-assembled construction devices and elements contemplated for small-size switch units such as that presented here.
- Number 10 in this drawing indicates the switch unit comprising a casing 11 with means 11a for its fitting in operation, a base 12 holding 12" fixed contacts, a moving contact 13 and a switch 14 for controlling the moving contact 13.
- the casing 11 is made of relatively flexible material.
- a small continuous external channel 15 open at the front, i.e., towards switch 14, and having several 15' corner drainage openings.
- the purpose of the small channel 15 is to collect liquids and condensate and discharge these outside so they do not penetrate inside the casing 11, towards the power contacts.
- the base 12 is made from a material different to that of the casing 11 so it is more resistant to heat.
- Said base 12 has a number of 12' side dentils which snap fit into special 11' holes in the sides of the casing so the two fasten together.
- the 12' fixed contacts consist of terminals to which the power leads are fastened; the base is made of material able to resist the heat generated during soldering of the power leads.
- the fixed contacts given the same dimensions of the switch casing, feature preferably a centre distance greater than that of known switches, of the same kind.
- the arm and closing strength of the moving contact are thereby increased and better results are achieved with regard to the amperometric capacity of the switch unit itself.
- the moving contact 13, housed in said casing 11, consists of a flexible metal foil, with a substantially asymmetric "C" shape which acts both as a positioning spring and a contact.
- the moving contact 13 is pivoted on a 12" fixed contact which rests on the other 12" fixed contact as a result of switch movement.
- Control switch 14 consists of two materials of different colour 14a, 14b. This two-component, two-colour aspect of the switch facilitates location, by means of the visible colour only, of the off or on part of the switch without requiring other means of indication.
- the control switch 14 is fitted in a special housing of casing 11 on which it is centrally pivoted. It features a small fin under the pivot point, turned inwards with respect to casing 11 and which controls the moving contact 13 in the known manner.

Abstract
Description
- The present invention relates to rocker switch units particularly for small household and electronic appliances.
- Various models of rocker switch units are already known, each with its own dimensional and constructive features.
- The present invention has for its aim the presentation of a rocker switch unit which, by arrangement and combination of parts, proves more advantageous in terms of manufacture, assembly and costs and is suitable for applying to 19 x 13 mm and 27 x 12 mm boring templates.
- Another aim of the present invention is to provide a rocker switch unit featuring never-assembled construction devices and elements contemplated for small-size switch units such as that presented here.
- Such aims are achieved by a rocker switch unit in conformity, at least, with claim 1.
- Greater details of the invention will in any event be clearer from the description hereunder with reference to the accompanying example drawings in which:
- Fig. 1 shows an enlarged perspective view of the rocker switch unit;
- Fig. 2 shows a side view of the switch unit;
- Fig. 3 shows an end view of the switch unit; and
- Fig. 4 shows a sectionla view of the switch unit according to line IV-IV in Fig.3.
-
Number 10 in this drawing indicates the switch unit comprising acasing 11 with means 11a for its fitting in operation, abase 12 holding 12" fixed contacts, a movingcontact 13 and aswitch 14 for controlling the movingcontact 13. - The
casing 11 is made of relatively flexible material. - It delimits a small continuous
external channel 15, open at the front, i.e., towardsswitch 14, and having several 15' corner drainage openings. The purpose of thesmall channel 15 is to collect liquids and condensate and discharge these outside so they do not penetrate inside thecasing 11, towards the power contacts. - The
base 12 is made from a material different to that of thecasing 11 so it is more resistant to heat. - Said
base 12 has a number of 12' side dentils which snap fit into special 11' holes in the sides of the casing so the two fasten together. - The 12' fixed contacts consist of terminals to which the power leads are fastened; the base is made of material able to resist the heat generated during soldering of the power leads.
- The fixed contacts, given the same dimensions of the switch casing, feature preferably a centre distance greater than that of known switches, of the same kind.
- The arm and closing strength of the moving contact are thereby increased and better results are achieved with regard to the amperometric capacity of the switch unit itself.
- The moving
contact 13, housed in saidcasing 11, consists of a flexible metal foil, with a substantially asymmetric "C" shape which acts both as a positioning spring and a contact. The movingcontact 13 is pivoted on a 12" fixed contact which rests on the other 12" fixed contact as a result of switch movement. -
Control switch 14 consists of two materials ofdifferent colour 14a, 14b. This two-component, two-colour aspect of the switch facilitates location, by means of the visible colour only, of the off or on part of the switch without requiring other means of indication. Thecontrol switch 14 is fitted in a special housing ofcasing 11 on which it is centrally pivoted. It features a small fin under the pivot point, turned inwards with respect tocasing 11 and which controls the movingcontact 13 in the known manner.
Claims (5)
