E-TEN1221 toggle switch ON-OFF DPST 4 pins 15A 250V red
The E-TEN1221 toggle switch is a two-position ON-OFF switch designed to switch two circuits simultaneously. Thanks to its load capacity of 15 A at 250 V AC, it is perfect for electrical devices, machinery, control panels, and DIY projects.
Key features:
- Two stable operating positions: ON-OFF.
- DPST contact configuration – simultaneous switching of two circuits.
- Contact load capacity up to 15 A at 250 V AC.
- 4 terminals for wire connection.
- Durable construction with a red lever.
- Designed for panel mounting.
- Compatible with a waterproof cover (sold separately).
Operation
The E-TEN1221 switch operates in a DPST (Double Pole Single Throw) configuration, allowing it to turn two independent electrical circuits on or off simultaneously with a single lever movement. This solution is often used where simultaneous disconnection of the phase and neutral wire or two separate power lines is required.
Application
- control panels and switchboards,
- industrial and workshop equipment,
- power supplies and electrical devices,
- electronic and DIY projects,
- modernization and repair of devices as a replacement part.
Installation
The switch is designed for panel mounting. A mounting hole with dimensions of 30 × 19 mm allows for quick installation in the housing. To increase resistance to dust and moisture, a compatible protective cover can be used.
How to connect the E-TEN1221 switch?
The E-TEN1221 switch has four screw terminals numbered 1, 3, 4 and 6. Inside, there are two independent contacts switched simultaneously (DPST).

- ON position: terminal 1 is connected to 3, and terminal 4 with 6.
- OFF position: both circuits are disconnected – between terminals 1–3 and 4–6 there is no connection.
The switch allows for simultaneous switching on or off of two independent circuits. It is often used to disconnect the phase and neutral wire, switch two power lines, or control two circuits at the same time.
