TLS-C Terminal Limit Switches

The TLS-C Cartop Terminal Limit Switch System is a highly accurate, maintenance-free replacement for old style mechanical TM switches and contacts that are often incompatible with today’s computer based control systems. State-of-the-art TLS-C eliminates noisy rollers and cams, cumbersome lever arms and the necessity for regular cleaning and adjustment.


Switches are mounted in a cartop box—while actuating magnets are mounted on brackets attached to the guide rail.

Clearances up to 1/2 inch (13mm) help maintain a high level of accuracy over the complete range of possible car movement.

Designed for computer based control systems’ need for reliable contacts at speeds up to 2,000 fpm (10m/s).

Use for Normal Terminal Slowdown Device, Emergency Terminal Stopping or Speed Limiting Device, Access Limit and Earthquake Car to Counterweight Switch.

Switch is direction-dependent with bi-stable memory.

Choose from 12 or 16 switch models (TLS-C-12, TLS-C-16).

Switches on 1 5/16 inch centers (33.3 mm)
