Kit includes low-voltage 1/2" diameter pushbutton test switch (two-wire) with integral charging indicator LED (2W-ITS) with bushings, tubing, tie-wrap, yellow wire with red stripe, screws and caution labeling.
This kit is primarily used with most emergency LED driver products for linear fixtures, like the BSL310.
Two-wire test switch/charging indicator LED lead wires are 6" long. They connect to the appropriate lead wires on the emergency unit as shown in that unit's installation instructions.
