The push-button switch that is commonly used to ON/OFF small power electric signal is widely used in all devices of the needs reception signal of telecommunication.In these push-button switches, a kind ofly be used to control wetting system, washing machine for example, push-button switch have can water-impervious structure, this seepage-proof structure can prevent that sealing enters in the switch contact, because if water infiltrates in the switch contact, short circuit when the switch contact will get rusty or work so.
Fig. 1 and 2 is respectively the plane graph and the cross-sectional view of conventional waterproof switch.This water proof switch comprises a shell base 101 and a clamshell 109, have fixedly contact 103 and 104, movable contact 105 on the shell base 101 and go between 102, housing 109 combines with shell base 101, housing 109 has with movable manner installs within it sliding part 108, is used for making movable contact to contact or disengage with fixing contact.
Describe traditional waterproof push switch in detail below with reference to Fig. 1 and 2.Form in shell base 101 on the bottom of enclosure space 110, the spaced apart from each other first fixing fixing contact 104 of contact 103 and second is arranged, 102 outsides of guiding to shell base 101 that go between are so that with the energy input and output.First and second fixedly contact 103 and 104 be connected to separately one the lead-in wire 102 on.The movable contact 105 of conductor flexibly is installed in first and second fixedly above the contact 103 and 104, and can move both vertically, so as to make first fixedly contact 103 and second fixedly contact 104 realize being electrically connected or break away from and be electrically connected; On movable contact, be provided with the movable contact block 111 of non-conductor, so that make the action of movable contact 105 more steady.With the adhesive-bonded fabric bonding agent with waterproof membrane 106 bond to shell base 101 above, thereby with space 110 sealing, rubber slab 107 is set on waterproof membrane 106, in order to protection waterproof membrane 106.Clamshell 109 is welding on the shell base 101, and sliding part 108 is positioned at clamshell 109, and can move both vertically, so that external force is added on the movable contact 105.
The number of assembling steps of above-mentioned push-button switch is described as follows.
Movable contact 105 is inserted in the enclosure space 110 that forms on the shell bases 101, the two ends that make movable contact 105 with second fixedly contact 104 contact.In this case, movable contact block 111 is placed on the movable contact 105, waterproof membrane 106 is the circular membrane sheets that downcut from cylinder, with vacuum absorption device waterproof membrane 106 is picked up, and move be put into shell base 101 above, then waterproof membrane 106 is bonded on the shell base 101, thereby form enclosure space 110.By above-mentioned steps movable contact 105 and movable contact block 111 are inserted in the enclosure space 110 of shell base 101 and utilize waterproof membrane 106 after enclosure space 110 sealings, with the clamshell 109 of built-in sliding part 108 be placed into shell base 101 above, and to pressing down, make closely contact between shell base 101 and the clamshell 109, then they are welded together, thereby finish the assembling of push-button switch.
Under the needs situation, when the user directly or indirectly pushes sliding part 108 in the push-button switch of assembling on the equipment of being installed in, first fixedly contact 103 and second fixedly contact 104 just enter connection status, signal can be imported.That is to say, when the user add a power for sliding part 108 by the direction of the arrow indication among Fig. 2 and with sliding part 108 when pressing down, rubber slab 107 that contacts with sliding part 108 bottoms and waterproof membrane 106 quilts are constantly toward pressing down, thereby with movable contact block 111 also constantly toward pressing down, so just make movable contact 105 be shifted downwards, thereby with first fixedly contact 103 contact, make first fixedly contact 103 with second fixedly contact 104 realize being connected.Thus, make closing of circuit, switching signal can 102 be added on the control assembly by going between.
