PURPOSE: To provide a means for easily laying a hold mechanism for holding the operation of the operating part of an equipment into hold state even when something is unexpectedly touched by push operation, and preventing the consumption of a battery or erroneous operation by an unnecessary operation. CONSTITUTION: When a first operating element 2 is reciprocated in non-hold state direction, the stepped part 2a of the first operating element 2 is caught by the end part 4a of a second operating element 4, and the first operating element 2 is laid into the locked state. Simultaneously, the hold state of an operating circuit is interlockingly released by a slide switch 7. The operating part 4b of the second operating element 4 is then pushed against a spring 3, whereby the stepped part 2a of the first operating element 2 is interlockingly released from the end part 4a of the second operating element 4, and the first operating element 2 is returned to the original state, or the hold state by the energizing force of the spring 3. |
