As shown in Figure 2, the assembling sequence of above-mentioned existing waterproof touch type switch is: shell 1-spring contact strip 2-double-faced adhesive tape 3-waterproof bulkhead 4-stem stem 5-loam cake 6.
The operation principle of above-mentioned existing waterproof touch type switch: when using waterproof touch type switch, switch series is associated on the controlled circuit by two lead-in wire 1a.When needing to connect circuit, available hand touches stem stem 5 tops, stem stem 5 is subjected to downward pressure, and this pressure passes to the top of spring contact strip 2 by waterproof bulkhead 4 and double-faced adhesive tape 3, and spring contact strip 2 deforms, make spring contact strip 2 contact with fixed touch plate 1b, make the control circuit conducting of control circuit board, thereby connect controlled circuit, after staff leaves stem stem 5, the control circuit of control circuit board still keeps conducting state, makes controlled circuit also still keep on-state; And when staff touches stem stem 5 tops again, stem stem 5 is subjected to downward pressure once more, this pressure passes to the top of spring contact strip 2 by waterproof bulkhead 4 and double-faced adhesive tape 3, spring contact strip 2 deforms, and makes spring contact strip 2 contact with fixed touch plate 1b, and the control circuit of control circuit board is disconnected, thereby disconnect controlled circuit, after staff left stem stem 5, the control circuit of control circuit board still kept off-state, made controlled circuit also still keep off-state.
The shortcoming of above-mentioned existing waterproof touch type switch is: its building block quantity is many, packaging technology complexity, manufacturing cost height.Particularly because the general volume of waterproof touch type switch is less, it is just bigger that numerous parts are fitted together difficulty.
Summary of the invention
This uses novel technical problem to be solved to be, overcomes the shortcoming of above-mentioned existing waterproof touch type switch, and the waterproof touch type switch that a kind of building block is few, simple in structure, water resistance is good is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the utility model waterproof touch type switch comprises: lead-in wire, shell, control circuit board, fixed touch plate, spring contact strip, waterproof core column and loam cake; Described lead-in wire is separately positioned on the both sides of shell, and the one end stretches in the shell respectively and is fixed on the inner bottom surface edge of shell and is connected with control circuit board respectively; Described shell upper end open, described fixed touch plate is arranged on the middle position on the inner bottom surface; Described spring contact strip is the back-off spherical shape, is arranged on enclosure, and its lower edge contacts with two lead-in wires respectively, and and fixed touch plate between leave certain intervals; Described waterproof core column be arranged on spring contact strip above; Described loam cake is with the upper opening sealing of shell, and stretch out from the hole of loam cake central authorities on the top of described waterproof core column.
Described waterproof core column is to be made by water proofing property and the good elastomeric material of retractility, both can carry out waterproof effectively, again can be to the enough pressure of spring contact strip transmission.
The beneficial effects of the utility model are: simple in structure, parts are few, simplified packaging technology, reduced manufacturing cost, and water resistance is good.Both can be used for common electric equipment, can be used for the high electric equipments of waterproof requirement such as washing machine again.
