MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series
SPECIAL APPLICATIONS
Gravity Return Side Rotary Switches (LSS)
LSS1H gravity-return, side-rotary switches have no return
spring mechanism. The weight of the actuating lever must pro-
vide the force to restore it to the free position. The 5 in-oz. max.
operating torque is useful in conveyor applications since it
enables operation by small or lightweight objects. Because the
head is unsealed, the LSS1H is classified as NEMA 1. However,
the switch cavity is sealed to protect the switch contacts.

Extra Low Torque Side Rotary Switches (LST)
LST1H extra-low torque, side-rotary switches have a low force
return spring and a maximim operation torque of 12 in-oz. It is
rated as NEMA 1 due to an unsealed head. The switch cavity is
sealed to protect the switch contacts.
