Sprecher + Schuh LA7-16-3753 Rotary Limit Switch

The Sprecher + Schuh LA7-16-3753 is a base-mounted rotary limit switch in the LA7 family, designed for industrial control applications where a defined electrical position is required as a shaft rotates. This 3-pole, 90-degree throw variant carries UL/CSA ratings of 16 A and supports three-phase horsepower ratings of 3 HP, 7.5 HP, and 10 HP depending on operating voltage, aligning with common motor and control circuits. The suffix 3753 identifies the changeover version of the 16 A, 3-pole option (the non-changeover 1753 and the 6-pole variants 1756 and 3756 exist as well). With base mounting, the LA7-16-3753 is intended for robust installation in tight spaces where a compact rotary switch is preferred for switching control circuits or interlocks. In practice, it functions as a mechanical position sensor and interlock component on equipment such as conveyors, packaging lines, and other automated machinery, enabling a reliable electrical signal or interlock as the shaft rotates. When selecting a Sprecher + Schuh limit switch for a 16 A, 3-pole, 90° throw requirement with a changeover option, the LA7-16-3753 provides the documented combination of base mounting, 16 A rating, 90° operation, and reputable UL/CSA certification within the LA7 family.
