Product overview This SZW26/LW2632/D202.2EF 32A universal changeover rotary cam switch is a 3 position 1 0 2 panelmounted transfer switch supplied with a protective box and rotary knob. Designed for two phase applications, it provides reliable manual changeover between sources and clear on off reverse positions for straightforward operation. Key benefits Clear manual changeover control: threeposition 1 0 2 knob gives fast, unambiguous switching between two sources and an off position. Durable switching performance: conventional heating current 32A and rated shorttime withstand current 360A for 1 second reduce risk of damage under shorttime fault conditions. Versatile voltage compatibility: rated working voltage AC240V and AC440V and rated insulation voltage 660V suit a range of panel and control installations. Compact and ready to install: panelready design with included box and plastic enclosure for simple mounting and protection. Applicationfocused ratings: supports AC23A, AC3, and AC4 use categories with corresponding rated working currents for typical switching tasks.

Robust electrical capability: Suitable for motor control and switching duties thanks to AC3 and AC4 ratings and specified shortcircuit performance. Easy integration: Standard panel form factor and included box simplify installation in control panels and distribution boards. Clear specification: All electrical ratings provided for correct selection in application. Typical applications Generator transfer panel: Manual changeover between utility and backup generator supplies for small generators and backup systems where a two phase changeover is required. Motor control and maintenance isolation: Use as a panelmounted isolator and control switch for two phase motors or machinery during setup and servicing. Industrial and workshop distribution boards: Manual source selection and load routing in distribution panels and control cabinets. Installation and use notes Confirm that system voltage and current ratings match the switch specifications before installation. Mount on a compatible panel with appropriate cutout and secure the included box to maintain enclosure protection. Use the provided rotary knob for clear 1 0 2 operation and lockout procedures if required by site practice. This SZW26/LW2632/D202.2EF 32A cam switch offers a practical, well specified solution for two phase manual changeover and panel switching tasks.
