Which of the following is NOT a name of one of the seven switches?

Explanation:
The question tests your familiarity with how railway switches are named by their function or mechanism. Among the options, the first three describe actual switch types or operating methods: a Dual Control Switch is a switch that can be operated by hand or power, a Double Slip Switch is a complex turnout that lets trains move between tracks at an acute angle, and an Electric Derail Lock Switch is a switch that includes a derail lock mechanism to secure the derail. The term Strobe does not describe a switch at all; a strobe is a signaling light, not a device that changes track alignment. Therefore, Strobe is not a name of one of the seven switches.
