Linear 2500-030 is an OEM replacement limit switch from Linear (also sold under the OSCO, Nortek, and Linear PRO Access brand names). OEM SPDT standard-size limit switch for open/close position sensing in Linear gate operators. Key attributes include SPDT contact configuration and Standard physical size. Compatible with the Linear slide gate operators and Linear swing gate operators families.
A: SPDT stands for single pole double throw. The switch has one common terminal and two output terminals - one normally open (NO) and one normally closed (NC) - that toggle when the actuator is triggered.
A: The 2500-030 senses the gate's travel position. When the gate reaches its fully open or fully closed position, the actuator triggers the limit switch, signaling the control board to stop the motor.
A: This is a standard-size limit switch. If your operator uses a mini or compact size switch, verify the physical dimensions against the original before ordering.
A: The switch is also described as an open limit switch, so one unit is typically dedicated to sensing the fully open gate position. A separate switch (or the same model) is used for the closed limit.
A: Inspect the switch for broken actuator levers, cracked housings, or terminals that fail to make continuity at the correct gate position. Use a multimeter to test NO and NC contacts while manually actuating the switch.
