Philmore 235B is a 3-position rotary switch with four terminals. It is typically used for on/off/momentary switching applications in a variety of electronic circuits. The switch has five terminals and a 6mm diameter round actuator. The terminals can be connected to a variety of components such as resistors, lights, and transistors. The terminals are labeled A, B, C, D, and E, with A, B, and C being the three positions. When the switch is in a middle position, two of the terminals make contact while the remaining three don't. This switch is rated for use in damp environments and can handle up to 6 amps of current at 120 volts.
