Figure 2. MICRO SWITCH™ LSX General Dimensions MICRO SWITCH™ explosion-proof switches are designed specifically for use in hazardous area applications. In addition to meeting explosion-proof requirements, the MICRO SWITCH™ LSX meets additional enclosure sealing classifications. This makes the LSX ideal for outdoor use or in adverse environments where a combination of explosion proof plus sealing requirements are needed. The MICRO SWITCH™ LSX enclosure is sealed for protection against corrosion, water, dust and oil, as defined in NEMA 1, 3, 4, 6, and 13. These enclosures also meet NEMA standards for hazardous type Div. 1 & 2, Class I, Groups B, C, & D; Div. 1 & 2, Class II, Groups E, F, & G. MOUNTING INSTRUCTIONS The LSX may be mounted using two 1/4-inch or M6 screws for clearance fit, or two 5/16-18 UNC bolts for threaded fit. Torque threaded fit bolts to 12 in-lb to16 in-lb [1.4 Nm to 1.8 Nm]. See Figure 2.

Figure 3. MICRO SWITCH LSX Mounting Hole Pattern A grounding screw is located on the right side. The internal grounding terminal must be used for the equipment grounding connection. After wiring, replace cap so that the o-ring gasket is fully seated. ADJUSTING INSTRUCTIONS: ACTUATOR HEAD To give flexibility in application, the actuator head may be positioned in any of four directions. Loosen the four captive head screws, place the head in the desired position, and then securely tighten the four screws. The screw tightening torque is 12 in-lb to 16 in-lb [1.4 Nm to 1.8 Nm].
