  • Publication number: 20250253106
    Abstract: The present invention provides a push button switch that prevents an occurrence of non-matching of contacts. The push button switch 1 includes a push-operatable and return-operatable push button 20, the first and second pairs of contacts C1, C2 that are respectively transferred to an open state by a push-in operation of the push button 20 and transferred to a contact state by a return operation of the push button 20, and a return-speed increasing means that applies and releases a load relative to the push button 20 during the return operation of the push button 20 and that functions to increase a return speed in the return-operation direction of the push button 20. The inclined angles R of the second inclined surfaces 241a, 242a of the respective engagement members 241, 242 is determined such that the second inclined surfaces 241a, 242a function as the return-speed increasing means.
