Federal Signal Switch Control Model SW200 offers the same quality and features of the SW300 with four SPST rocker switches. Switch 1 has 40-amp capability, and switches 2ââ‚¬"4 have 20-amp capability. Model SW300 has six lighted single-pole, single-throw (SPST) rocker switches for control of virtually any type of lighting function. Switch 1 controls rotating lights and comes prewired to a 40-amp relay and self-resetting circuit breaker. Switches 2ââ‚¬"6 have 20-amp capability and are fused on a 20-amp circuit. These five blade- type fuses are mounted on the back of the switch control housing and correspond in sequence to the switches they control. This makes it easy to find any blown fuse for replacement. The SW300 comes with plastic legends that apply to the police and fire markets. These legends are backlit, glowing a soft green for easy nighttime viewing, and can be easily popped out and replaced when control functions change. Legends include: rotating lights, flashing lights, compartment light and front light cutoff.
