SPDT Miniature Biased switches.
Momentary action - toggle springs back to centre (off) position when released.
Ideal for operating solenoid motors, such as point motors used on model railways.
- Hole required: 6.35mm
- Rated: 5A/28v DC
- 3 positons: ON/OF/ON
- H 9 x W 13 x D 7mm
- Pack 5
Switch Reference Guide - SPST, SPDT, DPST, DPDT
SP and DP refer to single pole and double pole, ST and DT refer to single throw and Double throw.
- SP: Single Pole, one circuit controlled by the switch.
- DP: Double Pole two independent circuits controlled by the switch which are mechanically linked.
Note: “Pole” should not be confused with “Terminal”. The DPST switch, for example has four terminals however is a Double Pole (DP) and not a four pole (4P) switch.
- ST: Single Throw, closes a circuit at only one position. The center position is off.
- DT: Double Throw, closes a circuit in the up or down position (On-On). A Double Throw switch can also have a center position such as On-Off-On.
- SPST - On-Off
- DPST - On-Off - Both load terminals can be energized at the same time. They are independent of each other and could be of different voltages.
- SPDT - On-On - Only one of the loads can be energized at a time
- DPDT - On-On - Functions like two separate SPDT switches operated by the same actuator. Only two loads can be On at a time.
- SPDT - On-Off-On - Only one of the loads can be energized at a time.
- DPDT - On-Off-On - Functions like two separate SPDT switches operated by the same actuator. Only two loads can be On at a time
