Wiring & getting started
- Position 1 (up)
Common (centre pin) connects to Circuit A (outer pin 1).
- Position 2 (down)
Common (centre pin) connects to Circuit B (outer pin 3).

Unlike the MTS-103, this switch has no middle "off" position — one circuit is always active.
- Typical use
Select between two circuits, reverse a DC motor, or switch between two signal sources where an always-on state is fine.

Common questions
What's the difference between ON-ON and ON-OFF-ON?
ON-ON (this switch) has two positions — up (circuit A active) and down (circuit B active) — with no centre-off, so one circuit is always live. The MTS-103 is ON-OFF-ON and adds a safe middle "off" position between the two.
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 x 0.75 thread with a locking nut to secure it to the panel.
Please note: For mains AC applications, installation must be carried out by a licensed electrician in accordance with NZ wiring standards.
