FAQ for Z-15GW4-B
What is the difference between Z-15GW4-B and Z-15GW-B?
Both are 15 A SPDT hinge-lever basic switches with screw terminals and 0.5 mm contact gap. The GW4 is the Low-force hinge lever variant and runs at a lower operating force than the GW (medium-OP standard hinge lever). Pick GW4 when the cam or dog can only supply a light trigger; pick GW for a standard cam with normal trigger force available.
Can the Z-15GW4-B switch DC and AC loads?
Yes. The same switch handles AC and DC up to the rated current at each voltage. AC rating is 15 A at 125 / 250 VAC resistive (1/3 HP at 250 VAC, 1/8 HP at 125 VAC motor). DC rating is 15 A at 8 / 14 VDC, dropping at higher DC voltage. For inductive DC loads, use the inductive load column, not the resistive, and add a contact protection suppressor across the coil.
How do I mount the Z-15GW4-B on a panel?
Mount the body with two M4 screws with plane and spring washers, tightened to 1.18 to 1.47 Nm each. If the switch mounts through a panel and the actuator hex nuts sit on the panel side, tighten those hex nuts to 2.94 to 4.9 Nm. Use the AP-B terminal cover to keep fingers and metal debris off the live terminals. Do not oil or grease the lever pivot.
