Introduction

The PBX - 8324 micro switch features a double-break snap-action mechanism with electrically separated circuits (Zb form), positive opening action per IEC 60947-5-1 Annex K, extended overtravel, enclosure protection ratings of IP67/IP65 or IP40 with sealed plunger, operating temperature range of -50°C to +85°C, ratings from 1 mA 4 V to 6 A 250 V~, long mechanical life, multiple connection options, cURus and CCC certifications, and compliance with applicable railway standards. It is a double-break snap-action switch with electrically separated circuits, featuring positive opening action on the normally closed contact (21-22), with the two circuits usable at opposite polarities. Models 83244 and 83245 are suitable for low-current (minimum recommended 1 mA 4 V) or medium-to-high current circuits; however, a single unit may only be used to switch one type of circuit throughout its service life.
