PURPOSE:To provide a delay switch with improved controllability and better appearance by providing a piano handle, and turning the switch on and off through a piano-touch operation. CONSTITUTION:In a switch circuit having a delay circuit which produces outputs for a certain time after currents are no longer detected by a current detection means, a push bottom handle 32 mounted on the upper portion of an ON-OFF push button switch 7 is pressed by a piano handle 43. The handle 43 is pressed by piano touch and the push button handle 32 is pressed down and a reversing handle is rotated so that a contact makes (or breaks) the circuit; the contact breaks (or makes) the circuit when the piano handle is pressed again. The switch can thus be turned on and off by a piano-touch operation and the controllability and the appearance of the switch can be improved. |
