The uniquely simple design of the vanguard combines a foot operated air bulb and a remotely located bellows to actuate an electric snap switch. The basic components are an air bulb, connecting tubing with brass fittings, bellows and a basic snap switch. The bulb can be up to 30 feet away, thereby isolating the electrically live switch. Environmental protection, long trouble free life, simple field replacement of components, application versatility and ease of interfacing.
