Abstract

1337686 Retractive switches; casings SWITCHES Inc 30 Nov 1971 [1 Dec 1970] 55540/71 Heading H1N An electric switch comprises a rigid housing part 18, Fig. 3 having an annular recess 28 containing a pair of spaced spring-blade contacts 30, 40 which are depressed into mutual engagement by a projection 78 on a flexible cover 76 when depressed. Recessed slots 44 provide for terminal wire connections to lugs 42 on the contacts 30, 40. One contact 30 may have radial ridges (62), Fig. 2 (not shown) engaged by a circumferential ridge (64) on the contact 40 to provide point contact. A central portion 52 of housing part 18 has recesses 38 supporting the connecting wires 48 to reduce the strain on the terminal connections.
