MSSTC11DA45 IMO Microswitch, Screw Terminals Roller Lever 24.6mm

Why Choose the IMO MSSTC11DA45 Microswitch?

The IMO MSSTC11DA45 is a compact industrial snap-action microswitch designed for mechanical position detection, end-of-travel sensing and machine control applications. Part of the IMO MSS Micro Switch range, it features a short roller lever actuator with a 24.6 mm radius, making it well suited to applications requiring positive actuation within restricted installation spaces.

The MSSTC11DA45 uses a snap-action changeover mechanism to provide rapid and repeatable electrical switching as the roller lever moves through its operating point. The rotating roller helps reduce sliding friction between the actuator and moving machine components, while the short lever provides a compact mechanical arrangement and positive actuation.

Featuring 1 NO + 1 NC changeover contacts and screw terminal connections, the MSSTC11DA45 provides flexible integration into industrial control circuits. Its actuator characteristics include 3.5 mm pretravel, 4.5 mm overtravel, a 0.4 mm movement differential, an operating force of 1.66 N and a release force of 1.28 N.

Key Advantages

• 24.6 mm radius roller lever provides compact mechanical actuation.
• Roller actuator helps reduce sliding friction against moving machine components.

Compact Roller-Lever Position Sensing

Microswitches convert mechanical movement into an electrical switching signal when their actuator reaches a predetermined operating position. The IMO MSSTC11DA45 uses a 24.6 mm radius roller lever and snap-action mechanism to operate its changeover contacts, enabling machinery and control systems to detect movement, confirm component position or identify an end-of-travel condition.

The short roller lever is particularly useful where a cam, plate or other moving component passes across the actuator in a confined mechanical assembly. Compared with longer lever variants, the 24.6 mm radius provides a more compact actuation geometry, while the roller helps reduce sliding friction during repetitive operation.
