Overview
MICRO SWITCH GK 系列钥匙联锁安全开关采用坚固耐用的金属外壳，广泛适用于监控闸门、护罩或门的位置。钥匙连接至闸门、护罩或门的移动部分。当闸门关闭时，要是插入至 GK 开关，指示安全位置（闸门关闭），机器流程可以开始。当钥匙插入至 GK 开关时，正向断开常闭触点保持关闭。打开闸门，移除开关钥匙。该动作能断开开关的常闭触点，并中断机器的控制电路。
GK 系列开关采用双重位置钥匙。钥匙可插入开关顶部或侧面，以使应用中的开关安装更灵活。四种不同样式钥匙和开关触点布置，可满足多数安全联锁钥匙开关应用要求。GK 系列开关设计有独特的摩擦功能，以用于固定钥匙。GK 系列开关已经过安全功能评估，包括 IEC 要求的 SIL3 安全完整性等级（SIL）61508-2：2010.
