How It Works
1
Position 1 (up)
Common (centre pin) connects to Circuit A (outer pin 1). Circuit B is open.
2
Position 2 (centre)
OFF — common is disconnected from both outer pins. Both circuits open.
3
Position 3 (down)
Common (centre pin) connects to Circuit B (outer pin 3). Circuit A is open.
4
Typical use
Select between two circuits, reverse a DC motor, or switch between two signal sources — all with a safe off state in the middle.
Please note: For mains AC applications, installation must be carried out by a licensed electrician in accordance with NZ wiring standards.

Wiring — 3-Pin SPDT
Pin 1 (outer)Circuit A output — active when toggle is in position 1
Pin 2 (centre / common)Common — connect your power or signal input here
Pin 3 (outer)Circuit B output — active when toggle is in position 3
The centre pin (common) connects to either outer pin depending on toggle position. Centre position = OFF (common disconnected from both). Use this to select between two circuits, switch direction of a DC motor, or control two independent loads from one switch.
Please note: 3-pin solder lug terminals. For mains AC applications, installation must be carried out by a licensed electrician in accordance with NZ wiring standards.

Please note: The centre OFF position makes this switch ideal for any application requiring a safe disconnected state between two circuits.
Common Questions
What's the difference between ON-OFF-ON and ON-ON?
ON-OFF-ON (this switch) has three positions — up (circuit A active), middle (both off), and down (circuit B active). ON-ON has only two positions with no centre-off. The MTS-103 is ON-OFF-ON, making it suitable for applications where you need a safe "off" state between the two positions.
How do I wire it to reverse a DC motor?
Connect motor + to pin 1, motor − to pin 3, and battery + to pin 2. Flicking the toggle reverses polarity to the motor, changing direction. Add a relay if your motor draws more than 2A.
What size hole do I need to drill?
6mm diameter. The switch uses an M6 × 0.75 thread with a locking nut to secure it to the panel.
