Indicator Installation

Indicator is positioned to fit to the NC-ON window of the cover and the spring is aligned to NO contacts.
Indicator is On when NC contacts are closed(at free position),then goes Off when NO contacts are closed(when actuated).
Every switch is shipped out of factory with this mode.

Indicator is positioned to fit to the NO-ON window of the cover and the spring is aligned to NC contacts
Indicator is On when NO contacts are closed(when actuated),then goes Off when NC contacts are closed(when released).
NO-ON mode and NC-ON mode can be switched to each other by rotating the indicator holder.

Set Position Indicator

The two convex surface indicators on the shaft housing show the operating zones for proper operation to help you do simple installation and maintenance. Too much over travel may cause short mechanical life due to possible damage to the switch mechanism.

Proper Zone
Too little Over travel, adjustment needed
Too much Over travel, adjustment needed
Too much Over travel, adjustment needed

Mounting Dimensions

Sealing/Mounting Accessory

One Side Action Mode

All side rotary switches of Standard type and High-Precision type can be set to actuate one side only.
Clockwise and counterclockwise mode is Available by rotating the plunger inside the operating head as shown in the picture to the right.

Every listing of over travel D series switches can be set to one side action mode by rotating the cam inside the operating head as shown in the picture below.

Operating Head Direction Change

<90˚ Incremental Rotation>

Many types of SZL-WL limit switches provide the function of head direction change with 90˚ increment. The operating head can be set to any of the four positions by loosening the four head lock screws as shown in the picture to the right. This function is applied to all side rotary lever types and SZL-WLD,P,E,G,H,J.
The head of over travel D series can be set to direction ① and ③ only.
