<p>An enable switch, comprising two microswitches (20), an operating member (2) swingable in arrow directions A and B about a shaft part (2a), a transmitting member (3) movable in arrow directions C and D, a contact member (4) movable in arrow directions E and F, a driven member (5) movable in arrow directions G and H, and a restriction part (1c) located at a position opposed to the contact member (4), wherein the swing of the operating member (2) in arrow direction B continued until the contact member (4) comes into contact with the restriction part (1c) is transmitted to the microswitches (20) and the swing of the operating member (2) after the contact of the contact member (4) with the restriction part (1c) is not transmitted to the microswitches (20), whereby the operability of the enable switch can be increased, safety can be increased by multiplexing a contact point mechanism, and the mounting work of the switch on a portable operating panel can be facilitated.</p> |
