The connector portion 3 attached to the main body 1 has a chamber 35 inside the insulating base 31, and accommodates the coil spring 33. The coil spring 33 is in pressure contact with one end of the lead terminal 34 in the lower portion of the chamber 35, and is in pressure contact with the base of the movable pin 32 serving as a contact in the upper portion of the chamber 35. The movable pin 32 is normally pushed up through the upper hole 36 of the insulating base 31. A slide cover 38 made of an insulating material is provided so as to cover the insulating base 31 and the movable pin protruding from the insulating base 31, and can slide up and down along a groove 37 of the insulating base.
