Abstract
The utility model discloses a button switch, which comprises a base and a bracket. A static contact, a moving contact, a spring, an upper push rod and a lower push rod are sequentially installed between the base and the bracket; the bracket made of PC or PC alloy or PA or PBT material is buckled above the base through a pin roll. The button switch provided by the utility model utilizes a ratchet between the upper push rod and the lower push rod to realize locking, the moving contact and the static contact are pressed to realize connecting and disconnection of the circuit. Compared with the POM material, the bracket made of PC or PC alloy or PA or PBT material has better impact strength and fire resistance, can bear repeated impact from the push rod, and has longer service life; the fire resistance can meet the safety requirement; the bracket is buckled on the base through a lug shaft and is convenient to assemble.
Description
Technical field
The utility model belongs to household appliance technical field, is specifically related to a kind of push-button switch.
Background technology
Push-button switch is the low-tension switch electric appliance that is used for cutting off and connecting control circuit.Generally promote lower push-rod, push moving contact and fixed contact realization deciliter in the base by the upper push-rod that is installed in the support, and then the break-make of control circuit.Last lower push-rod requires that as movable part good anti-wear performance and insulation property are arranged, support is as its support unit, need bear its pressing operation repeatedly, require material to have better impact strength, at present, all adopt the unified making of polyformaldehyde (POM) material, though have good anti-wear performance in use at the POM material, its impact strength is little, easily ruptures in the reality, influence the useful life of push-button switch equally, and do not reached the safety requirement.
The utility model content
At above defective, the purpose of this utility model provides a kind of push-button switch, makes it have longer useful life.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of push-button switch comprises base and support, and fixed contact, moving contact, spring, lower push-rod and upper push-rod are installed between base and the support successively, and described support employing PC or PC alloy or PA or PBT material are made, and are fastened on the base by bearing pin.
Push-button switch described in the utility model, the ratchet in the utilization between the lower push-rod is realized locking, pushes moving contact and fixed contact and realizes connecting and disconnecting of the circuit; Described support employing PC or PC alloy or PA or PBT material are made, and compare the POM material and have better impact strength, can bear repeatedly repeated stock of push rod, has longer useful life, anti-flammability can satisfy the safety requirement, and support is fastened on the base by gudgeon, ease of assembly.
Description of drawings
