Very high quality low-cost push-button switch capable of operating as either push-onpush-off locking momentary push only non-locking. The push-onpush-off action latching action is provided by a wire detent. To make the switch a momentary action switch non-latching action the wire detent is pulled from the latching mechanism in the switch body & placed on one outside edge of the switch. The other end of the wire detent must be left in under the spring as this prevents the plunger falling out.
